Myself and a friend were travelling towards Sheffield on the A629 Road on a November evening. As we passed a truck depot, we both noticed what appeared to be a bright egg-shaped object seemingly floating in a field to our left. It was around one hundred feet in altitude and quite large, but made no sou whatsoever. Both myself and my friend stopped our car to get out to observe the strange object from the roadside. Four other people who were walking at the side of the road also stopped to comment on the strange sighting and continued on their way. Several minutes passed and the object shot up into the sky at a tremendous speed without warning and out of sight within seconds. This manouvre alone convinced both myself and my friend that wht we saw was not of this world. I have never seen anything like it before or since this incident, and was a non-believer - but now I am seriously open minded to say the least. This story is fact and the first time I have reported it.
